Abstract

At present, the fuel assemblies of Light Water Reactors require mainly cost-effective production of electricity. The objective of in-core fuel management is to achieve the objective of minimizing the cost of fuel cycle using advanced models of core loading strategies. Current development is focused mainly on optimizing the design of gadolinium fuel, thereby to reduce the average enrichment of fuel assemblies and the binding of the excess reactivity at the beginning of the fuel cycle. This paper deals with the different ways to optimize fuel assemblies containing burnable absorber for PWR and VVER reactors. These calculations were made in SCLAE 6 code through TRION module.
